The DBH 8743 is a radial shaft seal built to hold lubricant in place where a rotating shaft exits a housing. With a 47 mm shaft, 81.02 mm housing bore and 17 mm height, it fits medium-sized rotating equipment. The Lx designation tells you it is a single-lip seal with a metal case. MR Industrial Accessories supplies this seal as a brand.

The part number 8743 belongs to the DBH line of radial shaft seals. Reading the dimensions in order: shaft 47 mm, housing 81.02 mm, width 17 mm. The Lx marking on the part indicates a metal-cased, single-lip design for rotating shafts. It presses into the housing bore, and the lip rides against the shaft surface.

Seals of this size show up in gearboxes, centrifugal pumps, electric motors, rollers and other power transmission assemblies. The job is always the same: keep oil or grease inside and keep dust, water and other contaminants out. In some machines it also acts as a secondary barrier between two areas that run at different pressures or carry different fluids.

Before ordering, confirm the three measurements against the old seal: shaft diameter, bore diameter and height. The shaft should be clean, with no burrs or deep scoring where the lip contacts it. Lubricating the lip before installation helps it seat without damage. Drive the seal in square to the shaft with a proper tube or driver, never by hammering on the lip, and follow the housing shoulder orientation.

If you need a cross for part number 8743, send the measurements of the seal you are replacing. We can check the same family or another brand we carry. The code stamped on the old part or the equipment model also helps us match it against the manufacturer's data.
